Fine particles and dissolved organics pass through any screen. A protein skimmer lifts them out as foam. Below: what it removes, how it is run, and what to check when the foam stops.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

Organic molecules and fine particles stick to the surface of air bubbles and rise as foam. A drum filter cannot catch particles smaller than its mesh, and no screen catches dissolved organics. In a freshwater trout RAS trial, adding foam fractionation gave the clearest water: a swirl separator with a foam fractionator cut total BOD by 40%, total COD by 27% and microbial activity by over 55% against a drum filter alone ().Aquacultural Engineering, 2025<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
